SNOWPLOW FOR LOCOMOTIVE OR RAILWAY ENGINES.

' Application filed November 13, 1925, Serial No. 68,854, and in Austria November 24, 1924.

This invention relates to improvements in snow-plows for locomotive or railway engines, designated to clear away thesnow from the line, as well as also in the stations and adapted to be quickly adjusted or suited to the railway-section or gauge, in order to free of snow the desired width of the line.

The essential feature of the present invention consists in that to snow-plow halves, which are preferably operated by steam and firmly attached to the kfront sideof the engine, are secured shovels, adapted to move round horizontally disposed axle-joints and to the sides of the said snow-plow halves are attached driven wings, adapted to be moved round vertically arranged axles. Preferably these wings can be raised and' lowered simultaneously and fixed in the desired position. f

Several modes of carrying out the present invention are illustrated by way of example on the accompanying sheet of drawings in which Fig. 1 shows in side view the forward end of a railway engine to which is attached a snow-'plow according to the present invention.

Fig. 2 illustrates the arrangement shown in Fig. 1 in plan view and sectional plan view.

Fig. 3 illustrates in elevation the attachment of the side-wings.

Fig. 4 shows on an enlarged scale the .valve for operating the driving cylinder.

Fig. 5 illustrates in side view the arrangement of the steam-supply pipes, leading from the drivers cabin of 'an engine tothe shovels and wings, which are' situated in the lowered position.

Fig. 6 shows the frontend of an engine with the members of the snow-plow in the inoperative or raised position.

Figs. 7 and 12 illustrate on an enlarged scale two modified constructions for raising t-he shovel-parts.

Figs. 8 to 11, 13 and 14 are'detail views.

In the embodiment shown in Figs. 1 and 2, firm snow-plow halves 2 are attached to the forward end 1 of the engine in such a manner, that they extend forwardly at an incline and diverge from the middle between the rails toward the latter. Shovels 4 are rotatably secured to the snow-plow halves 2 by means of links or joints'3, as shown in Fig. 1, the said shovels being suitably curved.

stiffening rails 7, which rest against the cross-frame of the engine. f

A steam-drive servesfor adjusting the shovels 4. The former comprises four steamcylinders, arranged inl pairs in the space enclosed by the snow-plow halves 2. The

steam-cylinders 9 are provided with two compartments, and by means of arms 10, pivoted tothe snow-plow halves 2 and with the aid of connecting rods 11, transmitthe' steam-powerto the shovels 4, which, as shown in Fig. 1, can be moved from the position in full lines into the position illustrated in dotted lines, whereby the wings are raised beyond the firm snow-plow section.

Wings 12 and 13, forming an extension of the shovels 4 at both sides, are movably secured tothe snow-plow halves 2 by means of links or hinges 14 and 15 respectively. The wings 12 and 13 are furnished with curved members 16, the bottom end of which is wedge-shaped (Fig. 3), and rollers 17, which are secured to suitable supports, rest against these wedge-shaped faces, so that the same roll olf the roller 17 withvthe wedgeshaped part .of the curved members 16 and are 'raisedy o-r lowered if the wings 12,- 13 are turned.y

As shown inFig. 2, the curved members form` effective stiffenings of the wings 12, .13 and were provided with recesses 18, which are engaged by locking bolts 19 (Fig. 22), in order to secure the wings 12, 13 in the adjusted position. The pressure of the snow acting on' the wings is transmitted by the same, by the curved members and by the locking bolts `to the frame of the engine. TheV locking bolts are arranged resiliently and close automatically, whereby the tension can be released from the drivers cabin, for instance by means of a foot-lever, in order to permit the rotation of the wings.l Fig. 5 shows the arrangement of such a foot-lever 20, which is operated against the action of a spring 21 and adjusts a connecting rod 'l2 and v1 3 respectively, movethe latter .cutev wardly or inwardly, whereby the wings are simultaneously raised .and lowered by the curved members 16 andthe fixed rollers 17.- lniitheraiscd position the .wings rest against the .cylinder 28 .ofz the engine, so thatvthesaine arezprotected againstanyobstacle. ln

the fully lowered position the bottom face ofthe wing extends about; one centinaetre,y belownt-he height of the rail,4 but the lolverl position-limit of :the wings canl .l be regulatedaccordingfto the wedge-angle of. the. curvedA members. gauge, the wings ma position.

The steamvsupply. :to ithe cylinders 9 and According tothe take up any desired 251and '26 respectively is effected :through steampipes `3O,and'3l respectively by means of a valve,illustrated in Fig. 4. The plug of .the valve is furnished with a 'rightangular. passage133 andY aninclined passage 34, which Vadvances with respect tothe passage .33, e.. g., it isopened in advanceduring the =rotationcottlie plugzand provides at for :anoutlet-inadvancerllherefore the inoperative side ofr the ypiston is relieved earlier, beforethe` operative side is subjected to pressure. .For instance if steam passes thronghwthe .passages '36..and'37 into the cylinder, thefpassage 38 onthe second side @inthe-'cylinder iswconnected, slightlyin. advance, vwith' .the exhaust :conduit The procedurek is reversed .whenfreversing-f the i'falvew` As shown in F ig. 5 the pipes130 and Slfxlead from the' drivers ycabin of the engine to therchange-valves; 32arranged in the same.

According `to the embodiments villustrated in Figs.' 7't-o14,ithe shovels 4 can be folded up, and down, as `welllas raised andloweled. The raising and-lowering motion 'of' the shovels 4, forinstance operated bysteam7 is the principalfinovement 'of the height-ad justment, while further: the folding move- Ament of ,the ,shovelsl is :rendered possible as :auxiliary movement, in order-.to `avoid a damage-to theshcvels inthe eventrof meeting an obstacle.

`Figs. 7 and`l2show twofmodes of. raising and lowering the shovels 4.` According to the construction jillustrated. in Figi 7, the shovels 4 slide on'iinedfguidefjaws44Lof the fixed snow-plow:halvesf2, at the outside and inside faces, by means of two movable aws 42 and 43 (F 9) Aconnected by screws. The outer-jaw r42pforms at the same time the .wedge-.support 6, shown in Fig. l, between the shovel 4 andthe Afixed snowfplovv halves 2 and is provided with an e* e '45 for the rotatable attachment `of the shovel 4. rllhns the latter is pivotally secured to the movable jaw. 43, so as to be foldedupand .down and rests against the wedge-surface of the outer jaws 42. Cylindrical .spiral Isprings 46 pull the shovels 4 vtoward` :the ,wedge-faces "42: and by .the saine` are` held against: any,- ,snow-presnre, :which may yact-:fromthe. bottom, while they gf'ieldupward in caseof. shocltslof great strength., suchas foi-.instance whenmeeting obstacles with .theleadingjaws 47 (Fig. .7),

and are automaticallyA l lowered again vafter Y having passed the obstacle.

. rlhe inner-jaws-43of eachshovel areprovided Vwith a'rack, andthe latter is :engaged by atoothed wheel 49, inountedon the driving shaft 48. AnfarmnO' is secured to-the driving shaft 48 and is connected withthe piston rodof a steam-cylinder 51,so .that on operatingthe :latterthe alrin 50` is rotatedfas shown kin F ig. l7,..and= raises. orolowers the racks ,43 bymeansfof the" toothedwwheels 49. Thereby the shovel 4 moves from the position ,indicatedl f in". dotted lines. i Thef' ysteamcylinder 5l is` operated in .similar manner-v as in the event of the steam-cylinders 9,25, .26 according to Figs. 4 and 5. Wedges 52 are provided ini order-tellin the'shovels 4 inl any convenient height, `the Aformer being-connect'l ed by afpull-rod53and areund'er theQi-nliuence of a cylindrical spiralspring-54- VThe Vpulhrod 53 cambe shifted.` from the driverls-cabin of the :enginebv-means 'of a lever arrangement 55, so that the two wedges f can be pushedunderneath-the racks 43.A and according to their position limitithedown- .ward movement jof the racks 43 according to requirement.' :The adjustment 1 of' -t-he `pullrod .53 .canbe fined in Aconvenient manner, for instance by means Y'of locking 1*bolts f provided inithed-niverls cabin .(not illustrated); The shovels 4v areturnished withirecessesf56 in order to pass underneath the railheadun theirA lowest 'positi-on.
